PHL Audio E17 - Manual

E17
APPLICATIONS
The main purpose of these models is sound reinforcement direct
radiation multi-way systems when the low freq. extension required
does not allow types SP1040/1050 to operate in good conditions.
Designed with higher Xmax capability types SP1060/1070 can be
X-overed from as low as 400 Hz when single or 300 Hz when used in
pairs, and will then exhibit all their sound quality potential.
DESIGN CONCEPT
PROGRESSIVE WAVE DIAPHRAGM optimized for low-midrange
extended frequency domain.
The M17/E17 Series design is based on the PROGRESSIVE WAVE
DIAPHRAGM mechanical behavior of the radiating area.
In this principle, the membrane is considered as a mechanical
transmission line which should receive a constant given velocity
together with critical damping properties to work properly.
This leading edge technology offers substantial sonic advantages.
Among them : very low mechanical energy storage in the cone
(so avoiding standing waves) which ensures coherent sound, fast
transients, stable sound imaging, high sensitivity, wide frequency
range and very-low directivity pattern.
COMPACT MAGNET SYSTEM. Its design has been specially
optimized to obtain maximum transducing efficiency while
avoiding unlinear behavior such as coil inductance variation with
position, flux modulation, harmonic distortion, rest position offset,
air compression, and off-axis voice-coil pushing.
Its design incorporates a T-shaped pole piece, and a flux
stabilization ring. It also takes into consideration demagnetization
at cold temperatures.
INTERCOOLER SYSTEM (patented). Entirely integrated into the
loudspeaker itself, the
INTERCOOLER SYSTEM extracts the heat
produced by Joule effect in the voice-coil by the means of an air
flow directed through the heatsink rims of the basket by the
motion of the dust-cap and the spider.
The gain brought about by this technology is over 20 % of extra
power, so for example, a 3”coil according to this design has
the same power handling capacity as a classical 4”one.
